IMPROVEMENT m HOlSTlNG AND CONVEYING APPARATUS.

Specification forming part of Letters Patent No; 177,572, dated May 16, 1876 application filed April 12, 1876. i

To all whom it may concern:

Be it known that I, FREDERICK ScHOLEs, of the city of Brooklyn, E. D., county of Kin gs, and State of New York, have invented a new and Improved Apparatus for Hoisting and Conveying, which improvement is fully set forth in the following specification, reference being bad to the accompanying drawing, in 'which' Figure 1 represents a longitudinal section leased, Fig. 3 is a plan or top view. Similar letters indicate corresponding parts; My invention relates to certain improve,

ments in apparatus for hoisting and conveyarm being made to project in a downward direction, and having combined with it a weight or spring which has a tendency to retain it at an angle to a perpendicular line or plane, so that whena bucket or sling, after having been hoisted, is attached to the arm, the latter is brought in a perpendicular plane or nearly so,

while for the purpose of detaching the bucket or sling, after it has been conveyed to the .desired spot it is only necessary to lift it a sufficient distance to clear the hook or other device by Which it is attached to the arm, when by the action of its weight or spring the arm is swung back to its original position and the bucket or sling may be lowered or deposited without obstruction. The tub or sling containing the material to be conveyed is hoisted by means of a rope, one end of which is fastened to the truck, and which carries a hoisting-block of ordinary form, while it is passed over a pulley mounted in the truck. This rope serves also to propel the truck along th railway.

The weight or spring, combined with the swinging arm for the purpose of retaining it at an angle to a perpendicular line or plane, in this example, has the form of a secondary form a hook, 0.

arm extending in a horizontal plane, or nearly so, and which has a hook or other catching device formed on it to engage with a stop affixed to one end of the aforesaid railway for fated on each side of the truck, which are in- 1 tended to rest on the railway on which the truck is placed, and by striking against suita ble. stops placed near the end of the railway opposite to the end above mentioned, prevent a forward movement of the truck, these two parallel arms being connected to each other and with the spring or weight arm as well as the supporting arm in'such a manner that the several arms are actuated by asingle movement, and the parallel arms are also raised when the supporting-arm is moved in a perperpendicular line.

In the drawing, the letter A designates a truck constructed according to my invention, the same being provided with wheels B B, and being, moreover, placed on two rails, U G, which, together with posts D, form an elevated way or track. This railway is preferably inclined, as shown. The letter E designates the arm which serves to receive and support the material to be conveyed by the truck. This arm is bent at one end to form a hook, at,

and at the other end is secured to the circum' ference' of a disk, F, which is secured to the truck by pivots b, so that the arm E swings on said pivots. The arm projects downward, as shown. To the circumference of the disk F is secured a secondary arm, G, which, like the swinging arm E, is bent at one end to The primary object of this armG is to form a spring or weight by whose action the swinging arm E shall be moved to and retained at an angle to a perpendicular line, as will be presently explained; but I do not wish to be restricted to the use of such perpendicular line, as seen in Fig.2.

adjacent post D, as seen in Fig. 1. The end of the railway at which the truck is thus fastened is intended to formthe loading-place.

The two arms E and G are arranged at such an angle to each other that when the hook c of the weight-arm G is allowed to catch over the stop 01, the swinging arm E'is brought out'ot' a perpendicular line, as clearly "shown in Fig. 1, and when a coal-bucket, H,

or a sling containing a package is attached to the arm E,-the weight of such bucket or package tends to bring the said arm E in a When the swinging arm E is thus brought in a perpendicular line, the arm Gr is'raised so as to bring its hook 0 out of engagementwith the stop d, and hence'the truck is automatically released. Inasmuch as by the weight or spring of the arm Gr a tendency'is given to the arm E to occupy an inclined position, the

bucket or other article can be readily'detached from the arm E by simply lit'ting the article a suflicient distance to clear and allow'such arm to move back, which it does'automatically when the article is lifted, whereupon the article may be lowered or'deposited in thedesired spot. The letters I I designate two'parallel arms, one situated on eachsideof the truck A, which serve to pre'vent" a forward movement otthe truck after it has been moved to the lower end of the track (3, as represented in Fig. 3. These arms I I are-bentin ward and pass through 'he sides of the truck; While they form the p vots on which 'the'"di.-k"F

' turns. I Such arms -I I consequentlypartake of the movement of the disk and of the arms E and G. The parallel arms I I act in conjunction withstops J J ,"secured" to each of the rails O O, in hindering a backward movement of the truck, and it is obvious that when the supporting-arm E-is in a perpendicular position, the'arms I I are raised from the track, and thus when a coal-tub or other weight is suspended'from the swinging arm E, the movement of the truck is unobstructed. K desig- "nates a rope, which'serves to elevate the'coaltub or other article to be conveyed or transported by the truck-A. One end of this rope is fastened to the 'truck; the rope is thence passed through ahoisting-block, L, and over a pulley, 'M, mounted in the truck to a'p'ulley,

N, arranged inthe adjacent post D; thence to a drum or Windlass. (Not shown.) The hoisting-block lu -is provided withia loop,;e,-whereby it may be connected to the swinging arm E, and with a hook, f, for the attachment of the selected article. If the article to be transported-is attached to theo-block L, and the blockis'thereupon raised'by'the rope K, the block can readily be attached to the arm E so as-to-release the truck. Whenthe truck is released it may be propelled over the tracks 0 O in one direction by its own weight, proyided thetrackis inclined, and in. the other direction bythe rope K. 1

It is apparent that the block L can be connected to the swinging arm E by simply lifting the block a sufficient distance and then allowing its loop to'drop'into'the hook of. the

arm.

"The "end 'of the rope =K 'is'secured to the 'trnck'A by means er a cross-piece, g, which'is made adjustable by being 'set in notches I formed in the :upper'edge'of the truck, as

shown, "and by this meansthe endrof the rope "can be adjusted -todifl'erent parts ofthextruok.

The object of this arrangement is to permit =ot' accommodating the-rope to the degree of inclination-of the'truck or of its railway.

1t may.be'remarkedth'atfor the books on' the ends of tyearms E and G, loops or' vari- "ous other' devices may." be "substituted. SThe arms, moreover, may 'be'co'nnected with each other" in "various'other ways besides by'the disk F, and,"'if desired, may be formed in one piece with eachot'her.

What I claim as ne\v,-"and" desire to secure by Letters Patent, is

LIA wheeled "truck, carrying a swinging arm, E, which isp'ro'videdwith' ahook or other equivalentdevice, and combinedwith a 'weightors'pring, by the action of whiclrit is held-at an angle to. a perpendicularline or plane, substantially as described.

2. The'coinbination of a wheeled truck, the

"swinging armE, andtruck-fastening arm G, the whole being arran'ged'to operate substantially as described.

3. In combination with a'wheeled' truck and the'arms E and G, the parallel arms I 1, arranged and operating' substantiallyas described. I 4. The combinatiomwithi a wheeledtruck 'and'thearms'E, Gr, and I I: 'ofthe rope 'K.

"hoisting-block L andpulley M serving to elevate'the goods, substantially as described.

In'testim'onythat I claim the foregoing, I have hereuntosetmy hand and 'sealthis 6th day of April, 1876.
